Description
The aarch64-pc-windows-msvc and aarch64-uwp-windows-msvc targets force panic=abort. @alexcrichton said this:
The AArch64 Windows backend didn't implement SEH unwinding when the aarch64-pc-windows-msvc target was first added, so I suspect this is the same as that. I haven't checked the LLVM backend recently to see if this works.
This looks related to #54291, which points at these now-merged LLVM changes:
It's possible that we do not need to force panic=abort anymore for arm64 Windows as a result. What's the best way to determine if this is still required?
